摘要
目的 探讨老年非酒精性脂肪性肝病(NAFLD)合并2型糖尿病(T2DM)患者血清三酰甘油葡萄糖乘积指数(TyG)、内脏/皮下脂肪面积比(VSR)和心脏代谢指数(CMI)变化及其临床意义.方法 2021年1月～2022年12月我院诊治的老年NAFLD合并T2DM患者98例和老年NAFLD患者98例,常规检测空腹三酰甘油和空腹血糖,计算TyG指数.使用内脏脂肪检测装置测量内脏脂肪面积(VFA)和皮下脂肪面积(SFA),计算VSR.常规检测腰高比(WHR),计算CMI.采用多因素Logistic回归分析影响合并T2DM的危险因素 结果 NAFLD合并T2DM组空腹血糖(FBG)、糖化血红蛋白(HbA1C)、胰岛素抵抗指数(HOMA-IR)和血清 TG 水平分别为(9.3±0.7)mmol/L、(9.1±1.6)％、(5.7±0.8)和(3.7±0.5)mmol/L,均显著高于 NAFLD 组[分别为(5.8±0.5)mmol/L、(6.1±1.2)％、(3.9±0.4)和(1.9±0.3)mmol/L,P＜0.05],而 HDL-C 为(1.2±0.2)mmol/L,显著低于 NAFLD 组[(1.5±0.4)mmol/L,P＜0.05];TyG、VSR 和 CMI 分别为(10.8±1.5)％、(0.9±0.2)％和(1.2±0.3)％,显著高于 NAFLD 组[(8.7±0.4)％、(0.3±0.1)％和(0.6±0.2)％,P＜0.05];多因素 Logistic 回归分析显示,TyG(OR=3.124,95％CI:1.101～8.862)、VSR(OR=2.601,95％CI:1.035～6.535)和CMI(OR=2.832,95％CI:1.061～7.561)升高均为影响老年NAFLD合并T2DM的独立危险因素(P＜0.05);37例重度NAFLD合并T2DM患者TyG、VSR和CMI分别为(12.4±1.9)％、(1.2±0.3)％和(1.7±0.4)％,均显著高于61例轻中度NAFLD患者[分别为(9.7±0.6)％、(0.7±0.1)％和(0.9±0.2)％,P＜0.05].结论 在老年NAFLD患者,检测并计算TyG、VSR和CMI可帮助筛查T2DM,值得深入研究.
Abstract
Objective The aim of this study was to explore the clinical implication of serum triglyceride-glucose index(TyG),visceral/subcutaneous fat area ratio(VSR)and cardiac metabolic index(CMI)in elderly patients with non-alcoholic fatty liver disease(NAFLD)and type 2 diabetes mellitus(T2DM).Methods A total of 98 elderly patients with NAFLD and concomitant T2DM and another 98 elderly patients with NAFLD were enrolled in our hospital between January 2021 and December 2022,and routine biochemical parameters were determined for calculation of TyG and CMI.The VSR was obtained from calculation of body fat detected by special apparatus.The multivariate Logistic regression analysis was applied for risk factor finding.Results The fasting blood glucose,glycosylated hemoglobin,the HOMA-IR and serum triglyceride level in NAFLD patients with T2DM were(9.3±0.7)mmol/L,(9.1±1.6)％,(5.7±0.8)and(3.7±0.5)mmol/L,all significantly higher than[(5.8±0.5)mnmol/L,(6.1±1.2)％,(3.9±0.4)and(1.9±0.3)mmol/L,respectively,P＜0.05],while serum high-density lipoprotein cholesterol level was(1.2±0.2)mmol/L,significantly lower than[(1.5±0.4)mmol/L,P＜0.05]in patients with NAFLD;the TyG,VSR and CMI were(10.8±1.5)％,(0.9±0.2)％and(1.2±0.3)％,all much higher than[(8.7±0.4)％,(0.3±0.1)％and(0.6±0.2)％,respectively,P＜0.05]in patients with NAFLD;the multivariate Logistic regression analysis showed that the TyG(OR=3.124,95％CI:1.101-8.862),the VSR(OR=2.601,95％CI:1.035-6.535)and CMI(OR=2.832,95％CI:1.061-7.561)elevation were all the independent risk factors for T2DM in elderly patients with NAFLD(P＜0.05);the TyG,VSR and CMI in 37 patients with severe NAFLD and concomitant 2DM were(12.4±1.9)％,(1.2±0.3)％and(1.7±0.4)％,all much higher than[(9.7±0.6)％,(0.7±0.1)％and(0.9±0.2)％,respectively,P＜0.05]in 61 patients with mild to moderate NAFLD and T2DM.Conclusion The detection and calculation of relatively simple TyG,VSR and CMI might be help for screening T2DM in elderly patients with NAFLD,and needs further investigation.
